DETAILED DESCRIPTION

A strut clip is disclosed comprising two rotatable elements disposed on each leg of the strut clip. The rotatable elements of the strut clip may rotate upon contact of their respective tapered lower edges with an inturned top wall of a strut. Once the rotatable elements enter into the strut, the rotatable elements may rotate back towards their original position, securing respective notches of the rotatable elements about downturned flanges of the strut. That is, any subsequent upward and/or downward force on the strut clip relative to the strut will not dislodge the strut clip from the strut. The disclosed strut clip may therefore be installed into a strut via downward force on the strut clip relative to the strut and any further fastening, such as by tightening a bolt, may not be required. A conduit, such as a pipe, may be inserted into the opening provided by the strut clip and supported by the strut clip and/or strut.

FIG. 1A depicts a perspective view of an exemplary strut clip embodiment in a first position. A strut clip 100 may comprise a first leg 102 and a second leg 104 detachably attached via an aperture 106. The aperture 106 may have a fastener 108, such as a nut, bolt, and washer, disposed through the aperture 106. A first rotatable element 110 may be rotatably attached to the first leg 102 at an aperture 112. The first rotatable element 110 may rotate relative to the first leg 102 via the aperture 112. The first rotatable element 110 may have a tapered lower edge 114 and a notch 116. The notch 116 may include an innermost edge 118 and a re-entrant edge 120. The innermost edge 118 may be flat relative to a local plane in the first position. The re-entrant edge 120 may be angled relative to a local plane. A first stop 122 may be disposed in the first leg 102 of the strut clip 100. The first stop 122 may limit rotation of the first rotatable element 110 via contact with an upper edge 124 of the first rotatable element 110.

A second rotatable element 126 may be rotatably attached to the first leg 102 at the aperture 112. The second rotatable element 126 may rotate relative to the first leg 102 via the aperture 112. The second rotatable element 126 may have a tapered lower edge 128 and a notch 130. The notch 130 may include an innermost edge 132 and a re-entrant edge 134. The innermost edge 132 may be flat relative to a local plane in the first position. The re-entrant edge 134 may be angled relative to a local plane. A second stop 136 may be disposed in the first leg 102 of the strut clip 100. The second stop 136 limits rotation of the second rotatable element 126 via contact with an upper edge 138 of the second rotatable element 126.

A first elastic element 140 may be disposed between distal longitudinal edges of the first rotatable element 110 and the second rotatable element 126. The first elastic element 140 may, in one exemplary embodiment, be a spring. The first elastic element may be disposed between a first protrusion 142 of the first rotatable element 110 and a second protrusion 144 of the second rotatable element 125. The first protrusion 142 may be substantially perpendicular to a front face 146 of the first rotatable element 110. The second protrusion 144 may be substantially perpendicular to a front face 148 of the second rotatable element 126. The first protrusion 142 may be substantially parallel to the second protrusion 144.

The stops 122, 136 are shown as two stops for respective rotatable elements 110,126. In some embodiments, the stops 122, 136 may be replaced by a single centered stop that restricts movement of both of the rotatable elements 110, 126. The position and number of stops 122, 136 may be adjusted along with the shape of the rotatable elements 110, 126 to limit rotation of the rotatable elements 110, 126 relative to the first leg 102.

FIG. 1B depicts another perspective view of the exemplary strut clip embodiment of FIG. 1A in the first position. The strut clip 100 may comprise the first leg 102 and the second leg 104 detachably attached via the aperture 106. The strut clip may also comprise a third rotatable element 150 rotatably attached to the second leg 104 at an aperture 152, a fourth rotatable element 154 rotatably attached to the second leg 104 at the aperture 152, stops 156, 158, a second elastic element 160, and notches 162, 164. The first leg 102 of the strut clip 100 may be identical to the second leg 104 of the strut clip.

FIGS. 2A-2B depict perspective views of the exemplary strut clip embodiment of FIG. 1A in a second position, i.e., engaged position. The rotatable elements 110, 126, 150, 154 of the strut clip 100 rotate relative to one another to fit into a strut (See FIG. 3) via downward force once engaged. Upon the respective notches of the rotatable elements securing about the downturned flanges of the strut, the exemplary strut clip may be affixed in position by a variety of means that may be well known in the art.

FIG. 3 depicts a front view of the exemplary strut clip embodiment of FIG. 1A in a strut. The strut clip 100 may comprise rotatable elements 110, 126 disposed in a strut 300. The strut 300 may include sidewalls 302, 304, a bottom wall 306, upturned top walls 308, 310, and downturned flanges 312, 314. Once the rotatable elements 110, 126 enter into the strut 300, the rotatable elements 110, 126 may rotate back towards their original position, securing respective notches of the rotatable elements 110, 126 about the downturned flanges 312, 314 of the strut 300. Any subsequent upward and/or downward force on the strut clip 100 relative to the strut 300 will not dislodge the strut clip 100 from the strut 300.

FIG. 4 depicts a front view of the exemplary strut clip embodiment of FIG. 1A. The strut clip 100 is shown in a first position. The strut clip 100 is in a first position before being inserted into a strut and once installed in a strut. The strut clip is in a second position (See FIGS. 2A-2B) as the tapered lower edges of the rotatable elements rotate from contact with the inturned top wall of the strut (See FIG. 3).

FIG. 5 depicts a side view of the exemplary strut clip embodiment of FIG. 1A. The strut clip 100 may be identical about a plane 500, depicted by dashed lines, between the first leg and the second leg of the strut clip 100.

FIG. 6 depicts a top view of the exemplary strut clip embodiment of FIG. 1A. The strut clip 100 may be identical about a plane 600, depicted in dashed lines, between the first leg and the second leg of the strut clip 100. FIG. 6 shows an exemplary compression spring as providing an outward torque to keep the first leg and the second leg in the first position. Other embodiments may utilize means for exerting a force between the first leg and the second leg, via for example, stored energy, to resist applied compression forces, or in the push mode, store energy to provide the push force and keep the first leg and second leg from further movement.

FIG. 7A depicts a front view of an alternate exemplary strut clip embodiment being inserted into a strut. A strut clip 700 may have a first rotatable element 702 and a second rotatable element 704 disposed in a first position for installation into a strut 706. The innermost edges 708, 710 of the notches 712, 714 of the rotatable elements 702, 704 may be flat relative to a local plane in the first position. The re-entrant edges may be angled relative to a local plane in the first position. Applying a downward force 716 on the strut clip 700 relative to the strut 706 may cause these angled innermost edges 708, 710 to contact inturned top walls 718, 720 of the strut. This contact causes a torque or momentum about an aperture 722, such that the rotatable elements 702, 704 rotate 724, 726 outwards towards the sidewalls 728, 730 of the strut 730.

The first rotatable element 702 may comprise a protrusion 732 substantially perpendicular to a front face 734 of the first rotatable element 702 and extending towards a front face 736 of the second rotatable element 704. The protrusion 732 may press against the front face 736 of the second rotatable element which causes friction and prevents the rotatable elements 702, 704 from rotating relative to one another as well as causing friction and preventing rotation between the second rotatable element 704 and a first leg 738 of the strut clip. In some embodiments, the front face 736 of the second rotatable element may comprise a depression, such as a dimple, for further securing the protrusion 732 of the first rotatable element 702. The second rotatable element 704 may comprise an aperture 740, shown in dashed lines, for receiving the protrusion 732 in a second position.

FIG. 7B depicts a front view of the alternate exemplary strut clip embodiment of FIG. 7A in a locked position in the strut. The protrusion 732 of the first rotatable element 702 may be inserted through the aperture 740 of the second rotatable element 704 in the second position. The first rotatable element 702 may not rotate relative to the second rotatable element 704 as it is restrained in rotation by the placement of the protrusion 732 in the aperture 740. Accordingly, any subsequent upward and/or downward force on the strut clip 700 relative to the strut 706 will not dislodge the strut clip 700 from the strut 706. The disclosed strut clip 700 may therefore be installed into a strut via downward force on the strut clip relative to the strut and any further fastening, such as by tightening a bolt, may not be required.

FIG. 8A depicts a front view of an exemplary first rotatable element 800. The first rotatable element 800 has a first edge 810, a second edge 812, a top 818, and a bottom 820. The first edge 810 includes a first notch 804 with a first innermost edge 806 and a first re-entrant edge 808. The first edge 810 also includes a first tapered lower edge 822 proximate the bottom 820 of the first rotatable element 800. The second edge 812 includes a first arcuate lower portion 814 proximate the bottom 820 of the first rotatable element 800. A lower portion 815 of the first rotatable element 800 includes at least a portion of the first arcuate lower portion 814, the first tapered lower edge 822, and the first notch 804. A first aperture 816 is disposed in a front face 802 of the first rotatable element 800.

FIG. 8B depicts a front view of an exemplary second rotatable element 830. The second rotatable element 830 has a third edge 840, a fourth edge 842, a top 848, and a bottom 850. The third edge 840 includes a second notch 834 with a second innermost edge 836 and a second re-entrant edge 838. The third edge 840 also includes a second tapered lower edge 852 proximate the bottom 850 of the second rotatable element 830. The fourth edge 842 includes a second arcuate lower portion 844 proximate the bottom 850 of the second rotatable element 830. A lower portion 845 of the second rotatable element 830 includes at least a portion of the second arcuate lower portion 844, the second tapered lower edge 852, and the second notch 834. A second aperture 846 is disposed in a front face 832 of the second rotatable element 830.

FIG. 9A depicts two exemplary rotatable elements 800, 830 in a first position 900 being inserted into a strut 904. The first rotatable element 800 may be rotated 920 relative to the second rotatable element 830 about a pivoting member 902. The second rotatable element 830 may be rotated 922 in an opposite direction as the rotation 920 of the first rotatable element 800. A downward movement 924 may be applied to the first and second rotatable members 800, 830 towards an opening in the strut 904. In the first position 900, a width 926 of the first and second rotatable members 800, 830 is less than a width 928 of an opening in the strut 904.

The strut 904 includes a bottom wall 906; sidewalls 908, 910; upturned top walls 912, 914; and downward flanges 916, 918. The bottom portions of the first and second rotatable elements 800, 830 may be inserted into the opening of the strut 904 in the first position 900.

FIG. 9B depicts two exemplary rotatable elements 800, 830 in a second position 930. In the second position 930, the first and second rotatable elements 800, 830 continue to be inserted into the strut 904 via a downward movement 936. The downward movement 936 may be a user pressing the disclosed strut clip into the strut opening. As the downward movement 936 force is applied, the arcuate portions 814, 844 of the first and second rotatable elements 800, 830 contacts the upturned top walls 912, 914 of the strut 904. This contact causes the first rotatable element 800 to rotate 932 relative to the second rotatable element 830 about the pivoting member 902. This contact also causes the second rotatable element 830 to rotate 934 in an opposite direction as the rotation 932 of the first rotatable element 800. This rotation 932, 934 causes the width of the first and second rotatable elements 800, 830 to be greater than the width of the opening in the strut 904.

FIG. 9C depicts two exemplary rotatable elements 800, 830 in a third position 938 in the strut 904. The first and second rotatable elements 800, 830 are fully inserted into the strut 904 in the third position 938, and no more rotation of the first rotatable element 800 relative to the second rotatable element 830 occurs about the pivoting member 902. The width of the first and second rotatable elements 800, 830 remains greater than the width of the opening in the strut 904. A gap 940 is present between the re-entrant edge 838 of the second rotatable element 830 and the downward flange 916 of the strut 904. Another gap 942 is present between the re-entrant edge 808 of the first rotatable element 800 and the downward flange 918 of the strut 904. If a force was applied in an upward direction away from the opening of the strut 904, the re-entrant edges 808, 838 of the first and second rotatable elements 800, 830 would prevent removal from the strut 904.

FIG. 9D depicts an exemplary strut clip 946 fastening a pipe 952 against the strut 904 in a fourth position 944. The first and second rotatable elements 800, 830 may be part of the disclosed strut clip 946. The strut clip 946 includes a first leg 948, a second leg hidden by the first leg 948, and a fastener 950. As the strut clip 946 fastens the pipe 952 to the strut 904 in the fourth position 944, the re-entrant edge 838 of the second rotatable element 830 contacts the downward flange 916 of the strut 904 and a gap 954 is created between the first arcuate lower portion of the first rotatable element 800 and the strut 904. The re-entrant edge 808 of the first rotatable element 808 contacts the downward flange 918 of the strut 904 in the fourth position, and a gap 956 is created between the second arcuate lower portion of the second rotatable element 830 and the strut 904. With the re-entrant edges 808, 838 of the first and second rotatable elements 800, 830 in contact with the downward flanges 916, 918 of the strut 904, no further tension or locking mechanism is required to maintain the position of the first rotatable element 800 relative to the second rotatable element 830 in the strut 904. The first and second rotatable elements 800, 830 may be removed from the strut 904 by removing the fastener 950 and/or pipe 952, rotating the first and second rotatable elements 800, 830 to the first position, and lifting the lower portions of the first and second rotatable elements 800, 830 out from the opening of the strut 904.
